In the Transtheoretical Model (TTM), the preparation stage (as applied to smoking cessation) is defined as planning to quit in the next 30 days plus having quit for at least 24 h in the last year. This study examined the value of prior quitting experience as a stage classification criterion by investigating whether prediction of making a quit attempt differed as a function of prior quitting experience.
One thousand and forty-six participants, all planning to quit in the next 30 days, in a randomised trial of the effectiveness of a telephone counselling and computer-generated tailored advice intervention were followed up at 3 months.
A multivariate predictive model had markedly greater capacity to predict making a quit attempt among participants with prior quitting experience (as defined in several different ways), compared to analyses of the overall sample. A previous attempt of 24 h in the previous month was associated with the greatest difference in prediction. A quit attempt in the previous year (the TTM definition) did not discriminate.
Recent prior quitting experience moderated the predictive capacity of some variables that influence smoking cessation. The findings provide some support for a stage model of smoking cessation but not its operationalisation by the TTM.
在跨理论模型（TTM）中，准备阶段（适用于戒烟）被定义为计划在接下来的 30 天内戒烟，并且在过去一年中至少有 24 小时没有吸烟。本研究通过调查先前戒烟经验是否影响戒烟尝试的预测，检验了将先前戒烟经验作为阶段分类标准的价值。
在一项电话咨询和计算机生成个性化建议干预有效性的随机试验中，共有 1046 名计划在接下来的 30 天内戒烟的参与者，在 3 个月时进行了随访。
与对总体样本的分析相比，具有先前戒烟经验（以多种不同方式定义）的参与者的多元预测模型在预测戒烟尝试方面具有明显更高的能力。前一个月有 24 小时的戒烟尝试与预测差异最大。前一年的戒烟尝试（TTM 定义）没有区分。
最近的先前戒烟经验调节了一些影响戒烟的变量的预测能力。这些发现为戒烟的阶段模型提供了一些支持，但不能支持 TTM 的操作化。
